Abstract
The main objective of this research is to analyze current problems and methods proposed for solving problems of design, operation and planning for the development of future sustainable electric power systems, taking into account the integration of renewable energy sources, the integration of heat and gas networks using highspeed communication channels. The author’s method of ensuring system stability and protecting the integrity of electric power systems is outlined. To ensure stable operation of future electric power systems, it is proposed to use methods of multi-level optimization and control of digital power systems, smart grid technologies and methods for processing vector measurements based on cyber-secure communication channels. It has been established that the proposed schemes make it possible to ensure the stability of the system and protect its integrity. In order to demonstrate the effectiveness of such approaches, an example is given of solving the problem of preventing rolling blackouts of the power system by purposefully separating/isolating the system based on the author’s twostage controlled isolation algorithm. It is shown that to solve the problems of modern electric power industry, it is effective to use new telecommunication technologies, means of ensuring situational awareness and schemes for protecting the integrity of systems based on modern methods of operations research and artificial intelligence. The multicriteria optimization method proposed by the authors uses minimization of the objective function of power flow disruption and takes into account restrictions on the consistency of generator operation. The method was tested on an IEEE test circuit consisting of 118 nodes. Test calculations confirmed that the method allows for minimal power imbalance and minimal disruption of power flows. Thus, the results of the work open up new opportunities for improving the monitoring and protection of future sustainable electricity systems, including taking into account the integration of renewable energy sources, heat and gas networks.
